The two games I have my eye on tonight are the Yankees vs. Mariners and Knicks vs. Rockets. All four teams feature lots of star power, which appeals to the DFS style of play Underdog provides. Here are some Yankees vs. Mariners and Knicks vs. Rockets predictions I have for tonight.
| Player | Pick |
| Todd Grisham | Lower Than 0.5 Hits |
| Logan Gilbert | Higher Than 6.5 Strikeouts |
| Karl-Anthony Towns | Higher Than 17.5 points |
| Amen Thompson | Higher Than 15.5 Points |
Grisham failed to record a hit against Luis Castillo yesterday and faces another tough matchup tonight in Logan Gilbert. I like Gilbert to record a high strikeout tally against a Yankees team averaging 9.75 strikeouts per game. In the NBA, Towns is due for a bounce back scoring game after two quiet outings. I predict Thompson has a big game due to the five inch height advantage he has over Jalen Brunson.
